2.6 General hazards and safety measures
The company operating the system must comply with the statutory obligations on occupational safety. In addition to the
safety instructions of this manual the safety, accident prevention and environment protection provisions applicable for the
system's range of use must be adhered to. The operating company must clearly define responsibilites and make sure that all
staff operating the system has read and understood this manual. The company also has to inform about hazards at regular
intervals. Personal protective equipment has to be made available to the staff. Maintenance intervals have to be respected.
Risk of physical injuries by high pressure or unexpected material leakage
•
Unexpected material leakage may result in burns. There is a risk of serious injuries or death and/or
damage to the hot runner.
•
There is also a risk of burns, if water gets onto or into the hot runner. If the water reaches dangerous-
ly high temperatures, the metal housing may burst and cause serious injuries due to emerging water
vapour or melting resins.
Safety measures
•
Make sure the hot runner system heats up evenly. Particularly for large manifolds it may be necessa-
ry to switch on nozzle and sprue bush heaters simultaneously, but later than the manifold heaters.
•
Make sure the nozzle tips and/or the gates are not blocked by solidified resin that has a higher mel
-
ting pont and that there is no humidity on the hot runner system, e.g. caused by a leaky temperature
control circuit (please see chapter „6.3 Start-up of a HPS III hot runner system“).
